Yes, that should work. Both are very similar and the serial ports
have the same logical device numbers so you should be fine.

I recommend to try v1 first, just to verify that/if it works
there, then you can concentrate on v2.

You cannot use the v1 code as is for v2, though. It must be ported. But
the code is pretty small and porting should be doable.

First you should test whether the super I/O works, i.e. if you get
serial output. That's esential for debugging.

Then you need to get the northbridge (RAM) working, then the southbridge
(for peripheral devices, e.g. network, USB)...
